I have found that numbers in scientific notation (e.g 9.8E-9) are incorrectly sorted or filtered by Galaxy. Looks like the negative exponent is ignored and so if you sorting something like P values (see example below) then you find these ordered above P=1 instead at the other end of the list where P is near zero. In the example below a KEGG list is ordered on column 5 in asending order by galaxy. If you scroll to the bottom of the list, however, you will see the smallest numbers all of which are in scientific notation. I should note that I can can copy this into excel and excel will properly sort scientific notation. So this seems to be a specific problem with Galaxy. I found this problem with both filtering and sorting functions of Galaxy.
